Theorem symgvalstructOLD 19439

Description: Obsolete version of symgvalstruct 19438 as of 6-Nov-2024. The value of the symmetric group function at 𝐴 represented as extensible structure with three slots. This corresponds to the former definition of SymGrp. (Contributed by Paul Chapman, 25-Feb-2008.) (Revised by Mario Carneiro, 12-Jan-2015.) (Revised by AV, 31-Mar-2024.) (New usage is discouraged.) (Proof modification is discouraged.)
